Use when analyzing GitHub Copilot experiment results: comparing agents, measuring success rates and cost-effectiveness, and inspecting session logs to identify failures. Covers Pier jobs and derived summaries.
Use when modifying the copilot-experiments library or CLI itself — adding or changing modules (models, pier_backend, pier_results, sessionlog, storage, report, scaffold, cli), writing tests, or updating the scaffolded experiment-repo template. Not for authoring experiments.
Use when creating or editing a GitHub Copilot experiment in this repository: defining Harbor/Pier task directories and Pier JobConfig YAML.
